You really know times are tough when even the world's cutest polar bear doesn't have any job security. Knut the polar bear literally wallowed in the dirt today after officials from the Berlin Zoo announced that they could no longer afford to keep him. Naturally, Berliners are outraged and 21,000 of the city's dwellers have signed a petition asking for Knut to stay. The Berlin Zoo says that Knut must leave by 2010, when he is expected to be transferred to a zoo in Gelsenkirchen where there is a young female polar bear named Lara. [Daily Mail]
